Emissions testing

Where can I get an emission test?

Find a test station at Applus+ Technologies, Inc. — they’re contracted by the State of Washington to provide vehicle emission testing. There are also some individual businesses that are authorized to perform testing.

Fleets may be able to do their own emissions testing. Learn more about fleet emissions testing(Department of Ecology).

Who needs to have their vehicle tested?

If you live in these counties, your vehicle may need testing every 2 years:

What if my vehicle is required to be tested but it’s out of the emission test area?

When your vehicle returns to the emission testing area, you’ll have 15 days to get it tested.

What if I'm going out of state for an extended period of time?

If your residence is still in Washington, but you’re going to school or living out of state for a few months, make sure you get your emissions test early. If you know your emissions test will be due while you’re gone, you can have it done within 365 days of the tab renewal date.

What are the requirements for military personnel?

Federal law requires your vehicle to be tested regardless of where it’s registered if:

You drive on a military base,

Within an emission inspection area,

60 days or more a year.

Any questions should be referred to your military base.

How soon can I renew my vehicle tabs after it’s tested?

The testing station sends us your results electronically. In most cases, our records will show your vehicle passed within 2 hours.

If you renew online, you should be able to renew a few hours after the emission test.

If you renew at an office, our records should be updated by the time you arrive. However, we recommend bringing a copy of your test results in case you arrive before your record’s updated.
